Cold Retreading Equipment TechnologyStep 1: Choose a tire that can be refurbished from a scrap tire. Can be done manually on the ground, can also be completed by the machine. The tire inspection machine is needed to turn the tire on the machine.

Step 2: After choosing a tire for retread, move to the grinding machine to grind, during this step, make sure there is no stone or any other debris on the tire, polish the adhesive tire layer until it is left with 3-2mm, the device can automatically control the distance. Machine required: Grinding Machine.

Step 4: The fourth step of the fetal cavity repair: in the expansion of the tire repair machine will expand the internal cavity of the tire cavity, the tip of the wound was repaired, different sixe of the wound layer is different. There is a distinction between wires. Required machine: tire repair machine, electric repair drill

Step 6: Our tires were punctured with sharp objects during the exercise, after the above repair the wound has been dealt with, there will be few millimeters in the depression, depression will need to fill the rubber, or in the tire speed, empty void fizz parts. So you need to use a rubber extrusion machine. Machine required: squeeze machine (glue gun), rotating frame

Step 7: In the rubber pad in milking strips after the need to put in the tire rubber (plastic pad), in order to ensure the grinding surface (i.e. tread) with trend rubber vulcanization. The required machine: on the rubber frame, automatic rotation.

Step 8: In the end of the pad, and then on a layer of trend rubber, tread rubber is the main renovation material, but also after the renovation of the ground contact with the ground. Machine: tread press. A good tread is better than a new one.

Step 9: Dismantling the pack envelope in dismounting machine, because when it the tire curing pressure is needed, to create the best physical condition is inflation, but now the inflatable tank technology cannot achieve uniform pressure, so in order to uniform pressure envelope appeared. Is the necessary material for tire retreading. Required machines: envelope disassembly machine.

Step 10: The inner tube, the steel ring cushion belt: disassembly machine with the mat on the belt, this is the simple manual machine, and then loaded on the rim. In order to install steel ring when tank pressure and pressure tube extrusion has a fixed support tube, tube or flexible, unable to form sulfide physical conditions. Required machines: wheel-dismounting machine.

Step 11: On the cycle frame: at this time has been completely packaged tires, put on the cycle of the queue, waiting for the tire is vulcanized, and then into the vulcanization. Required machines: suspension rails.

Step 12: Pay attention to curing fast joints, installed tube and envelope to avoid pretending, into the compressed air, and then start curing, curing at a temperature of 115 degrees Celsius for 3.5 hours. Vulcanizing tanks are 4, 6, 8, 10, 12, 16, 24, ranging from 30, according to the production capacity matching. The 4 is the largest one-time can pack 4 truck series tire 12R22.5, 3.5 hours after it is 4 12R22.5 tires, but the width of 12.22.5 is relatively large, since it can be installed 4 of this specification, the smaller tires can be installed at 6. The autoclave and a parameter called 12.00R22.5 tire diameter, height of 1.2 meters, the height of the tire, which is not put in. But in order to make the best use of the resources of the volcanize, our machine is 1.5 meters in diameter. If more than this height cannot be cured, it has to be customized, according to tire height custom, such as the tire diameter of 4 meters outside the giant engineering tire, and then I can be more than 4 meters inside the tank. Required machine: automatic control vulcanizing tank.

Step 13: Factory inspection: after delivery inspection, after strict inspection can be factory. Can be replaced by high-pressure testing machine, can greatly improve the quality of the factory. Required machines: tire pressure tester.
